Application filed January 3, 1912. Serial No. 669,295.

. T all whom it may concern:

Be it knownthat I, WVALTER D. TUSTEN, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county "of Kings and State of New York havefinventeda newand 1m:

proved Chain, ofwhich the following is a full, clear, and exact description.

My invention relates. to an improvement in chains, and particularly to the construction of the linksthereof; and it has forits object to provide a ,novelandsuperior device of this kind which can beused inithemak ing ;of Watch chains, braceletsand'other articles intended to be used for ornamental purposes.

Reference, .is to .be .had tozthe accompanying drawings forming a. party of this specification, inwhich the same characters of reference indicate the same parts, in. all, the

views.

Figure l is a perspective, viewof a chain made in accordance withmy invention and serving to carry a watch, the whole being. shown in position upon a ladys wrist; Fig.

scale, of the chain which is illustrated in-position inFig.-1*; Fig. 3'is alongitudinal vertical sectional view of one of the linksof the chain, the plane oflsect-ion being indicated ofthelink being shown in closed relation;

Fig. 4: is a view similar to Fig.- 3, showing the parts extended; and Fig. dis a longitudinal horizontal view taken onthe curved line 55 of Fig.4.

, My. improved chain consists of a. number of links made in sections movable with respect to each other, to permit the chain to be distended whenever desired, as, for instance,

bracelet or armlet, so as to enable it to he slipped over the-handinto position. The linksl are connected by. means of pivots or eyelet-s to-solid links 2, and-these links may beof any desired shape ordesign, and may be studded with diamonds or other gems to add to the ornamental efiect. The watch which the chain carriesis shown at 3,-and thiswatch isoofithe opemface type, as indicated, andis flanked on either side by the links 2,. which are arranged in alternation with the ex'tensible'links 1 over the entire lengthofthe chain, asFig, '2-illustrates;

Each of the links'lcompiisesa Urshaped section 4, which has a pair of parallel arms 6, connected by a. transverse portion 5, form ing the base of the U. This section 411s made in one piece, and is made solid, and'it receives between the, armsi6, thereof another section 7, which is hollow and "is seconnected to theU=shaped section t that itcan be moved, "longitudinally with respect thereto. Viewed from. the, top, the sections tand 7 are straight, butviewedfrom the side they will, be. bent, to conform to the,,wea rers arm when used in a bracelet, as shown. The sec tions 4:,and7 have eyeletSlB joined to their.

opposite ends for convenience in joining the links of the chain together. As stated above, thesection 7 she-110w, andit may besquare or rectangular in cross-section, according to whether a, broad or narrow link isdesired. This sect-ion is provided withslots 9, having closedends, these slotsfbeinglocated in the opposite sides of the section 7, adjacent the endto which the eyelet 8 is attached; and it is also provided with a slot 10 in oneof the sides, this slot being located adjacent the opposite or inner end of the section 7, andbeing open at one end as shown. -When formed in this way the section 7 will be open almost entirely on one of its sides, owin g to the alined slots 9 and lOformed in that side, but on the other side it will'lbe closedover substantially the inner half of its length. i

Thenumeral 11 represents a spiral spring whichisfhoused by the section/7, one end of this springbeingengagedbya pinf12 atthe' inner end ofthe section, to hold the spring in place, and the other end thereof abutting against a transverse pin 13, which is mounted in the outer ends of the parallelarms 6 of the othermsection 4, and passes through the slots9 in the opposite side of the sect-ion 7 The pins 12 and .13 serve to compress the spring llwhen the sections ofthe link 1. are extended; and, the pin 13/ further} serves *to keep theouter ends of the armswfi from spreading, in addition to serving as part or the guiding means forthe section by which the spring is. carried. I i

The arm. v6 :of thesection t which' is located adjacent the side of the section- 7 in which the slot 10 is formed, .is provided with a PatentedMay21, 191.2 J

short guide pin 14:. This guide pin is?lo'- i the pin 13 as a pivot. It does not engage or interfere with the spring 11 when the sections 4 and 7 are distended; and the pins 13 and 14 by always engaging the inner section 7 at two separated points, serve to keep the sections 4 and 7 in substantial alinement when the chain is stretched.

The arms 6 of the section 4: may be broad or narrow, as desired, and may be chased or worked by hand on top to give the same a suitable ornamental appearance. The section 7 will be closed on top, as shown in Fig. 3, and this part of the inner section may also be Worked for the same purpose. I may also mount diamonds or other gems in the tops of the arm 6 and the top of the section 7 when a jeweled chain is wanted.

From the above description it will appear that the construction of my link is both strong and simple, comprising but few parts, and these parts are so made and connected together as to reduce to aminimum the liability of the link getting out of order or broken. The sections of each of the extensible links will always be held in substantial alinement with each other, owing to the arrangement of the guiding means shown; and all of the parts which permit the relative movement of the links in the manner described are completely ineased to prevent the same from injury.

I wish to have it understood that the drawings and description of my invention are illustrative only, and that I do not care to be limited to the necessary details of the construction, except in so far as is indicated in the accompanying claims; and I also desire to have it understood that while my chain is described above as being employed in connection with articles worn for ornamental purposes, it is by no means limited to such uses, as will be readily perceived.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. An improvement in chain links, comprising a pair of extensible sections, one of said sections being substantially U-shaped, and the other of said sections being received between the arms of said U-shaped section, resilient means carried by said other section, a pin carried by the outer ends of the arms of the first-named section passing through said other section and engaging said resilient means to permit said sections to have relative movement, and means carried by one of the arms of said first section and extending into the second section in position to clear said resilient means, to prevent one of said sections from rotating around said pin as an axis, whereby the said sections will be maintained at all times in substantial alinement.

2. An improvement in chain links, comprising a U-shaped section having parallel ing with the same, said second pin prevent-' ing the second-named section from rotating around the first pin as a pivot, whereby the said sections will be maintained at all times in substantial alinement with each other.

3. An improvement in chain links, com-' prising a U-shaped section having parallel arms, a second section received between the arms of said U-shaped section, said second section being hollow and carrying resilient means on the interior thereof, a stud or pin mounted in one end of the said second section to engage one end of said resilient means, a pin mounted in the arms of said U -shaped section and extending through said second section and engaging the other end of said resilient means, whereby said sections will be secured together but will have relative movement, and guiding means carried by one of the arms of said U-shaped section and extending into the first-named section at a point remote from the pin carried by the arms, said guiding means terminating short of said resilient means to avoid interfering therewith, whereby the second section will be prevented from tilting with respect to the U-shaped section around the pin carried thereby as an axis, so as to maintain the said sections at all times in substantial alinement with each other.

4. An improvement in chain links, comprising a U-shaped section having parallel arms, a hollow section received between said arms, said hollow section having slots with closed ends in its opposite sides adjacent the outer extremity thereof, resilient means carried by said hollow section, said section having means to engage one end of said resilient means to hold the same against movement, a pin carried by the arms of said first section extending through the slots in the opposite sides of the second section and engaging the other end of said resilient means, whereby said sections will be secured together but will have relative movement, said hollow section having a third slot in one of its sides adjacent the inner end thereof, and guiding means carried by one of the arms of the first section and extending into said third slot, but terminating short of said resilient means to avoid interfering therewith, wherebythe sections will be prevented from rotating with respect to each other around the said pin asan axis, and will be held at all times in substantial alinement with each other.

5. In a link of the kind described, the combination of a pair of extensiblesections, means carried by one of said sections and engaging the other section, resilient means engaging the other section and said firstnamed section to permit said sections to have relative movement, and additional means carried by the first-named section and engaging the said second section in position to clear said resilient means, to prevent said second-named section from rotating about the first-named engaging means as a pivot.

In testimony whereof I have signed myv name to this specification in the presence of 15 two subscribing Witnesses.
